摘要： Methods and systems for performing multi-domain network slice selection and approval are provided. According to one aspect, a method performed by a Network Slice Selection Function comprises: receiving, from a requesting entity, a request for a network slice for use by a client device; upon determining that the network slice selection requires approval, identifying an Authorizing Network Function (ANF) for authorizing a network slice for the client device; determining a trust status of the ANF; identifying, based on the trust status, a network interface to use when communicating with the ANF; sending a slice selection authorization request to the ANF via the identified network interface; receiving from the ANF an approval status of a network slice; determining, based on the approval status and approval conditions, an allowed network slice; and sending, to the requesting entity, information including the allowed network slice.

摘要： Methods and apparatus for controlling the transmission of user data over an NAS of a telecommunications network. An AMF includes a receiver configured to receive NAS policy control data determined by a PCF. The NAS policy control data identifies a user, is based on the user's subscription to the telecommunications network and includes one or more authorization parameters identifying whether the user is permitted to transmit user data over the NAS. The receiver also receives from a UE, or an AS, an NAS transmission request identifying the user and requesting transmission of user data over the NAS. An NAS transmission authorizer controls whether the transmission of the user data over the NAS should be authorized based on the authorization parameters and the NAS transmission request.

摘要： An apparatus for user plane function, UPF, allocation is described. The UPF is configured to provide a Protocol Data Unit, PDU, connectivity service between a terminal device and a data network on a user plane, and the allocation is based on control information associated with an individual logical PDU entity. The control information defines priority information indicative of a priority of the PDU entity relative to other PDU entities and pre-emption information indicative of at least one of whether the PDU entity is capable of being pre-emptively allocated to a UPF over other PDU entities served by that UPF, and whether the PDU entity when served by a UPF is vulnerable to being re-allocated for pre-emptively allocating other PDU entities to that UPF. The apparatus is configured to detect an event that requires UPF allocation to a first PDU entity, to select a first UPF, wherein the first UPF is serving one or more second PDU entities, and to determine, for the selected UPF, insufficient resources for serving the first PDU entity. The apparatus is also configured to perform, responsive to determining the insufficient resources of the selected UPF, an evaluation of first priority information associated with the first PDU entity relative to second priority information associated with the one or more second PDU entities and at least one of first pre-emption information associated with the first PDU entity and second pre-emption information associated with the one or more second PDU entities. The apparatus is further configured to trigger, dependent on the result of the evaluation, allocation of the first PDU entity to either the first UPF or a second UPF.

摘要： The invention relates to a method, by a policy controller 100, for generating policy rules for data packet flows in a communications network. The policy controller 100 has access to a policy database 130 and stores a service level agreement. The service level agreement contains a plurality of different service level identifiers, each service level identifier being associated with a set of conditions that govern the policy rules to be applied to the data packet flows in the communications network. The method comprises the following steps: An authorization request is received for a data packet flow, the authorization request comprising service information for a service and a service level identifier. The policy database 130 is accessed and the set of conditions associated with the received service level identifier is determined. Further, based on the determined set of conditions, a policy rule to be applied to the data packet flow is generated. Policy controller 100 is configured to generate policy rules based on a third party or company profile, with the third party company being able to influence which policy rule should be selected by the policy controller. The authorization request may be received directly from an application function, AF 200. An input unit 230 is provided via which the third party can define and agree upon the service level agreement with an operator of the communications network. A policy control enforcing function PCEF 51 can interact with the PCRF 100 in order to enforce the policy rules.

摘要： Systems and methods are disclosed herein for event notification in a core network of a cellular communications system. In one embodiment, a method performed by a first Policy and Control Function (PCF) serving an Access Management (AM) policy association for a User Equipment (UE) wherein the first PCF is comprised in a core network of a cellular communications system comprises subscribing to an event exposure service of a second PCF serving a Session Management (SM) policy association for the UE. The method further comprises, responsive to subscribing to the event exposure service of the second PCF, receiving a report from the second PCF. In this manner, separate deployments of the first and second PCFs are enabled and still the first PCF serving the AM policy association for the UE can implement AM policies for the UE, e.g., based on UE data usage, e.g., of specified service bundles.
